To all/whom it mayconcem:

Be it known that I, WALTER THOMAS, a

, subject of the King of Great Britain, residing forms of gasroducing fuel, such as low grade coal, co e, oil, tar, peat,'saw-Iiust or refuse-wood, garbage, and other organic substances.

The a paratus is comparatively simple, andsupp emental parts such as a carburetor and checker brickwork ordinarily used for super-heating effects, are dispensed with.

The gases are generated in three adjoining connected chambers or com artments into which the fuel is admitted an these are proterior construction; Fi

vided at the bottom with valved pipes for admittmg all or steam, and at the top with as-eduction pipes, one for conducting pr0- ucer gas into a holder alongside the generator and the other for conveying water-gas or carbureted water-gas into another and separate holder, while blowers are rovided for forcing in air, and returning pro ucer gas throughthe generator for enriching it.

The construction, arrangement, and o e'r-I ation of parts are as hereinafter descri ed and illustrated in the accompanying drawi s, in which:

igure 1' is a plan view of the apparatus;

Fig. 2 is mainly a side elevation, a portion being shown in section for illustration of in 3 is an elevation of the side op osite that s own in Fig. 2, Fig. 4. is a vertica cross section on the hne 4 4 of Fig. 1; Fig. 5 is a vertical cross section on the line 5+5 of Fig. 1.

Reierrin particularly to Figs. 1 and 2, A, B,,B in icatc three chambers or compartments iorrecei'vingfuel from which gas is to be genera-ted.- These chambers or compartments are elongated verticaljland arranged sideby side, bein separated y partitions 1, which are'provined' at thetop with transverse passages}, which permit the flow of gasfiromthe s de chambers B, B", into the central chamber l propose to employ in this apparaitasany gas pro using fuel, but it may beparticularly adapted for refuse saw-- dust or refuse woo by cutting away the par- 5 servefor introduction of a bar for removing olinke'rs from the grates 4. .At the top 0 dotted lines 3, in

each chamber there is provided an opening 7 .having 'a' cap or cover 8, for admission of fuel.

Theash-pits of the several chambers A, B, B. are provided with openings 9, as shown in Figs. 4 and 5, for removal of ashes. At the to of the central chamberor compartment there is a passage-10see Fig. 2-- the same being surmounted by a stack or head 11-, from which 'p' cs 12 and 13 lead in opposite directions. e pipe 12 is for conveying ofi producer-gas into'a gas-holder C, which'may be located at any required distance from the generator, and the pipe 13 is for conveying water-gas, or car urete water-gas, into a similar gas holder C.

vided for conveying oilinto the top of-the central chamber A. a .As shown in Figs. 2'

and 3, the terminals of these pipes are in the form of nozzles 14 directed downward and at a slight angle so as to discharge convergentl into the chamber Aand in proximity to ti iepassages 2 that communicate with the side chambers B, B. I Air is forced into each of the chambers by means of a pipe 15 having right angular. branches 15 arranged as shownin Figs. 4 and 5, the'same having nozzles that terminate just below the grates 4. The ,pi e 15 is located on the back or rear side and elow the base of the generators and extends alon the same, bein provided at its-outer en with a fan or b oWer 16see Figs. 1, 2, 3.

In Figs. 4 and 5 I show a steam pipe 17 having three branches 17, 17 and 17, which lead to the ash pits of the several chambers A, B, B. By this means steam may be'discharged' beneath the rates, either alone or simultaneously with it e discharge of air from the'pipes 15, 15 Producer-gas which is located at one end of the generator and connected with the producer-gas pipe 12 and-a pipe 19 that extends along side of ,jtheseveral generating chambers and is pro v ded with a series of horizontal branch ,pipes or nozzles 19-*see Figs. 4 and 5the i5.

i era] chambers, so that the producer-gas may same discharging into the ash pits of the sev- 'be carried up through incandescent fuel, as

, will he presently described.

' In connection with theseveral pipes or conductors for air, steam, and air, heretofore described, I employ a series of valves which are connected by rods with levers 20, all of i which, for convenience of access and opera tion, may be arranged together, or side by side, as shown in Figs. 2 and 4. Thus, the

- valve-cover 21 of the gas-head 11, of central chamber Asce Figs. 4 and 5is pivoted at one side and connected by a link 22, with a rod 23sec Fig. 1in turn connected with and adapted to be rotated by one of said levers similarly, the valves 24 and 24 of gas-eduction pipes 12 and 13 are connected with, and operated by, rods25 leading to and connected with others of the levers 20.

As shown in Figs. 2 and 3, a rotary valve 26 ,is applied to, the air-pipe 15 contiguous to the fan or blower 16, and this is operated by a rod 27 also connected with one of the levcrs '20. Each of the branch pipes 15 connected with the air-pipe 15, is similarly provided with valves 28 that are operated by rods 29 connected with certain levers 20. The pipe 19 through which theproducer gas forced by-*the fan 18 when required to be enriched, is provided with a valve 30 operated by rods 31, and a lever suitably connected therewith. Each of the branch pi es H1 connected with the pipe 19 is provi ed with a-valve 32 and these several valves are operated by rods 33 connected with certain levers 20.

It should be understood that this apparatus will ordinarily be operated as a suction apparatus; in other words, a suction fan (not shown) will be connected with a top portion of the gas-holders or gasometers C and C. On the other hand, the suction fan may be dispensed with and the apparatus may be used on the pressure system.

I will now briefly describe the general oporation of the a paratus.

The gas -pro( ucing fuel is placed in all I three generating chambers A, B, B, and

ignited at the grate, and the stack valve 21 a of the central chamber is opened and fan 16 is started so that air is blown through the pipe 15 and its branches 15 into the several chambers beneath the grates thereof. When the fuel inthe several chambers has become incandescent the'stack valve 21 is closed, an

it need not be opened again, since all the producer gas may be, by subsequent blowing 'or blasting, conveyed by the pipe 12 into the holder C. Thus, as soon as the stack valve is closed, the producer-gas is rapidly generated and carried off through the pipe 12, as will be readily understood. In such case, it

is obvious that the valve of pipe 13, located adjacent to the head or stack 11, must be closed. To produce water gas, the fuel being incandescent in the several chambers, A, B, D, steamis admitted by pipes17, 17 17, beneath the grates, and the valve of producer pipe 12 being closed and the valve of the educti'on pipe 13 being open, the watergas produced in the chambers will be conveyed into the holder C. It will be 0bserved that in all these operations the gas from the side chambers B, B enters the cen-. tral chamber through thepartition openings 2. In order to make carbureted water gas, the fuel, being incandescent as before; steam is admitted under the grate of the center generator A, and oil is sprayed in at the same time through the nozzles 14*, and mingles with the wateras proper, and the mixed gases pass latera y through the passages 2 into the two side chambers B, B and then down through the incandescent fuel therein, thus becoming a fixed or permanent gas which is taken off by the pipe 19, through the branches 19* of said ipe and thus conveyed into the holder C. "l hus it will be seen that if Water --gas only' is required, steam is turned on in aH the chambers, and the watergas passes out at the to through the pipe 13 into holder 0; .but if the gas is to be car bureted, then steam is admitted to the center chamber A only, and the mixed ases ass into the side chambers, and then own through the grates thereof and through the pi ies 19, 19 to the holder-C.

f it is required to enrich theproducer-gas that has been received into the holder or gasometer C, it is brought back by the fan 18 and forced through the pipes 19, 19, into the gas-generating chambers, where it meets oil vapors introduced by the nozzles 14 and thus passes enriched or carbureted over into the gas-holder C. v

Near the junction of the roducer-gas eduction pipe 12 with pipe 19, Fprovide the former with a valve 34 for closing it when required, and in such case the fan 18;,draws the producer-gas back through branchpipe 12.
